'Il Claims. This invention Vrelates to window constructions particularly for use in barns, warehouses, shops,`

openings. Further and more detailed objects l lL and advantages will be disclosed in the course of the following specication, reference being had to the accompanying drawing, wherein: l

i Fig. 1 is an elevation of my improved window construction as seen from the inside of a building and with the sash'in'closed position.

Fig. 2 is a sectional` elevation on line 2-2 in Fig. `1.

Fig.V 3 is a sectional elevation similar to Fig. 2,v

`but with the sash in partly swung open position,

Y V the lower portion of the View being broken away.

Fig. 4 is a sectional elevation similar to Figs. 2, and 3, but showing the sash in a more advanced open position.

lig. 5 is an enlarged detail section on line v Fig. 6 is a perspective elevation of a portion of the structure, with glass panes removed and other parts broken away, this view illustrating the relative arrangement of various members when the sash is in both tilted and raised position.

, Fig. 7 is an enlarged detail sectional plan View` on` line 1 1 in Fig. 4, but with portions-of the sash stay or securing arm broken away. A9 Fig. 8` is an enlarged detail section illustrating `the grip connection between the stay and sash when the sash is in the raised position shown in Fig. 6.

` The frame and sash parts ofthe device may be made of either wood or metal but I have W here illustrated only a metal construction nasmuch as metal especially lends itself to a window of this design, being light, strong, and easily installed, and to this end I employ iron or steel bars which are Welded or otherwise suitably connected and are of angle or T-iron material to further assist in rigidifying the respective units. Referring to the various figures ofthe drawing particularly and by reference characters, A 5? designates generally the rectangular window `upper cross bar I I.

frame which is secured in the building wall and includes a sill 9, stiles or side bars I0, and an The members 9, I0, and II arejall preferably formed with outer edge flanges I2 to facilitate securing the frame in the wall 5 opening, and bars It and II are all provided with inner anges I3 against which the outer face of the sash stops when closed. The sill 9 also has an integral inner flange, It, which, however, is spaced inwardly from the plane of flanges I3, v10 as shown in Figs. 2, 4, 5, and 7, to forma recess I5 to tiltably and releasably receivethe nange `It ofthe sash designated as B.

The sash unitB is of rectangular construction to iit within frame A and into closing en- 1 5 gagement outwardly against anges I3. The side bars I9 and top and bottom bars 2i) and ZI of the sash are connected by mullions I'I forming the openings in which lights or panes' I8 are secured in any suitable manner. The upper end of the sash B may be swung inwardly from the frame A, as shown in Figs. 3 and 4, the lower end pivoting on the upper edge of sill flange I4. This arrangement allows ventilation through an upper opening (between bars Il and 20), and triangular side openings, while the angle of the sash tends to deflect rain and snow, and the overlap of sash flange I6 with respect to sill flange I4 serves to prevent water leakage inwardly over the sill. v

The sash is releasably secured by a stay or lock frame C, which is generally U-shaped in form having angle iron side arms 22 connected by a cross bar 23. The bar 23 may be of any suitable cross sectional form and has for its ob- 35 jects to insure simultaneous movements of the arms 22, to cooperate with the arms to form grips for engaging the sash, and to serve as a handle for manipulating the stay frame.

l The side or vertical flanges of the arms 22 have their ends, opposite from bar 23, pivotally secured, as at 24, to the inner upper ends of the stiles I. The other anges of the arms are inwardly notched, as at 25, to selectively receive the ends of the upper ange of sash rail 2|] (see 45 Fig. 3), to thereby secure the sash in more or less open, inwardly tilted positions. 'Ihe sash is released from the notches 25 bylifting the stay frame to approximately horizontal positions at which time the sash may be moved freely 50 under the notched flange. It may here be noted that when the sash is in closed position, the stay frame drops down in front of the sash, asin Figs. 1 and 2, and at such time the ends oi the notched stay flanges adjacent pivots 24 effectlve- 55 against the outer faces of stile flanges I3.

ly lock the sash in the frame A to prevent opening of the window from the outside of the building.

In addition to the inward tilting and adjustments of the sash I also provide for vertical adjustments, as shown in Fig. 6, to thereby effect substantially greater window opening clearance when the same is desired. As previously noted the sash B is not pivotally anchored or attached to the frame A, but merely seats in the recesses I5 while ange I6 overhangs sill flange I4 to tilt thereon, the swinging connection being maintained by the weight of the sash only.

When it is desired to elevate the sash, as shown in Fig. 6, to obtain clearance under the sash also, then the sash is rst released to the position shown in Fig. 4, at which time it rests against the stayframe bar 23 and is in position to be lifted upwardly through inwardly opposed recesses 26 formed in the ends of the stay frame C between the bar 23 and outer lips 21 of the notched flanges of bars 22. The size of the openings 26 is such that the sash may be freely lifted or pushed upwardly therethrough. The opening is sufficiently restricted, however, so that when the sash is released its weight and the Weight of the stay frame will tend to spread the lower angle therebetween, producing a bite or grip on the sash between lips 21 and bar 23, as

illustrated in Fig.V 8. As the stay frame C is free tomove on pivots 24 under its own weight, it will be self-adjusting on the sash as the latter is pushed upwardly. When it is desired to lower the sash it is only necessary to first slightly raise the stay frame, to release the bite or grip, and then hold it so raised with one hand while the other hand partially or completely lowers the sash under gravitational action. To insure proper guiding action of the lower end of the sash with respect to the Stiles I, when the sash is raised and lowered, it is provided at its lower outer corners with fingers 28 which are welded or otherwise suitably secured thereto and guide The recess formed by these ngers must of necessity be sufficiently large to permit tilting of the sash without binding.

It is understood that suitable modifications may be made in the structure as disclosed, provided such modications come withinY the spirit and scope of the appended claims. Having now therefore fully illustrated and described my invention,.what I claim to be new and desire to protect by Letters Patent is:

1. The combination with a window frame, of a sash mounted for vertical adjustment in the frame and with its upper end tiltable inwardly on a horizontal axis to open the window, a generally U-shaped stay member having its arms pivotally secured to the frame adjacent the sides thereof and with a connecting cross bar extending transversely ofthe sash, said stay member arms having opposed parts engageable with opposite surfaces of the sash to releasably grip and secure the same in vertically and tiltably adjusted open positions.

2. The combination with a Window frame, of a sash mounted in the frame for vertical adjustment therein and for tilting movement on a horizontal axis, and stay arms pivotally secured to the frame and engageable with the sash to secure it in selected tilted positions, said arms being operative to lock the sash in closed positions, and

frictionally grip side parts of the sash to support the sash in selective vertically adjusted positions.

3. 'Ihe combination with a window frame, of a sash mounted in the frame for vertical adjustment therein and with its upper end swingable inwardly from the frame on a transverse horlzontal axis, a generally U-shaped stay member extending across the inner side of the sash and with its arms pivotally attached to the frame near upper corners thereof, said stay members' having means for slidably engaging the sash and for producing a position retaining grip thereon under the action of gravity tending to angularly spread the stay member with respect to the sash.

4. The combination with a window frame, of a sash mounted in the frame for vertical adjustment therein and with its upper end swingable inwardly from the frame on a transverse hori- Zontal axis, a generally U-shaped stay member pivoted to the frame and passing laterally and inwardly of the upper end of the sash to embrace the same, said stay member being swingable downwardly into a depending position against the sash, when the latter is closed, to releasably lock the same, and means at the outer end of the stay member for slidably receiving and frictionally engaging the sash to secure it in adjusted positions.

5. The combination with a window frame, of. a sash mounted in the frame for vertical adjustment therein and with its upper end swingable inwardly from the frame on a transverse hori- Zontal axis, a generally U-shaped stay member pivoted to the frame and passing laterally and inwardly of the upper end of the sash to embrace the same, said stay member being swingable downwardly into a depending position against the sash, when the latter is closed, to releasably lock the same, and means at the outer end of the stay member for slidably receiving and frictionally engaging the sash to secure it in adjustedv positions, and means connecting the sash with the stiles of the frame adjacent the tilting axis of the sash to maintain pivotal and sliding engagement of the sash with respect to the frame.

6. The combination with a window frame, of. a sash mounted in the frame for vertical adjustment therein and with its upper end swingable inwardly from the frame on a transverse horlzontal axis, a generally U-shaped stay member pivoted to the frame and passing laterally and inwardly of the upper end of the sash to embrace the same, said stay member being swingable downwardly into a depending position against the sash, when the latter is closed, to releasably lock the same, and means at the outer end of the stay member for slidably receiving and frictionally engaging the sash to secure it in adjusted positions, the sill of the frame having an upstanding longitudinal flange, and the lower rail of the sash having a flange adapted to outwardly overhang 'the sill flange;

7. The combination with a window frame, of a sash mounted in the frame for vertical adjustment therein simultaneously with tilting movement on a horizontal axis, and means attached to the frame and inuenced by the weight of the sash to adjustably grip the sides thereof at selected points above the tilting axis to support the sash in vertically adjusted positions, said means comprising a pair of arms each being pivoted at one end to the frame and having its other end provided with a recess engaged by a side bar of the sash.
